I just noticed this morning that there was what seemed to be a third British Airways flight - called BA15A, that apparently departed at 8am as BA16D to London. This was in addition to the regular BA9 and BA15 arrivals.

Anyone know the story? I heard that BA16 has been delayed 2 hours also.

from what i can tell , Monday nites BA15 from heathrow did not depart unitil Tuesday @19.24 local time ( went tech??) , so as it was due in Syd yesterday , it did'nt arrive until today 0635 , this flight is currently due to arrive Heathrow today thursday @ 20.14 London time, as BA16D

Thanks very much everyone, much appreciated.
I did notice that yesterday [Friday] it had the same BA15D flight, that according to the Sydney Airport site, left at 6am.
Anyway, It was a bugger to have missed the chance at 3 BA jumbos.
